After using the same sneakers for over 10 years (yes, I did say 10 years), I decided that my knees and my sneakers needed to be upgraded. After looking around and reading reviews, I decided on the Nike Free 4.0 in the very beautiful Anthracite/Black color. I like the sleek look of the sneaker without screaming that its a running sneaker in bright fluorescent colors. I can use them for working out and running. A review will soon follow.
